If you plan on buying a Blu-ray player in 2011, don’t be surprised if the back panel is lacking a component video output. A surprising number of mainstream 2011 Blu-ray players, (such as the Panasonic DMP-BDT210, Samsung BD-D5700, LG BD670, to name a few) are omitting the red, green and blue video jacks, which means buyers will have to rely on HDMI for high-def Blu-ray video signals.
